A Catalogue of iStar Extensions

Abstract: iStar has been extended since its initial proposal in the 90's. It is worth noting that since 2016 the language notation is under standardisation. However, new extensions continue to be proposed. The search for previous extensions and its constructs can be a starting point in the proposal of new ones. So, to ease the identification of the previous extensions and its constructs is essential to next proposals. Motivated by this situation, the objective of this paper is to present a catalogue of iStar extensions.… Show more

“…We believe the adaptations of this method can be used during the proposal of new iStar extensions to propose the new symbols carefully. A catalogue of extensions can help reuse and avoid symbol redundancy and overload [11]. Also, the adapted method is better used as part of a systematic process for extensions creation [34,35].…”

“…O escopo da nossa pesquisa é delimitado ao uso do framework i* [Yu 1995], para representar o modelo de metas, e ao paradigma OO, pois o nosso conjunto de heurísticas para a rastreabilidade para trás [Moura 2017] considera características específicas de programação orientada a objetos (POO). O i* foi escolhido por ser um framework bem difundido na literatura [Dalpiaz et al 2016b] e com inúmeras extensões i* (vide catálogo 1 [Gonçalves et al 2018]).…”

“…Além disso, a relação meios-fim é o ponto chave para mapear a variabilidade com a semântica praticada em nossa pesquisa. Este framework também é bastante difundido na academia (DALPIAZ; FRANCH; HORKOFF, 2016b) e possui várias extensões catalogadas 7 ((GONÇALVES et al, 2018)) com diferentes finalidades. Não utilizamos a versão 2.0, pois entre as mudanças realizadas, estão a junção dos relacionamentos meios-fim e decomposição de tarefa em um único relacionamento denominado refinamento, cuja semântica difere parcialmente dos relacionamentos substituídos.…”
